I am an evolutionary biologist interested in how plants adapted to radically different environmental conditions upon colonization of new ecosystems.  I am especially interested in the genomic changes associated with the transition from terrestrial to aquatic environments.  

Because internal and external microbial communities are invariably intertwined with plants in natural environments, I am also interested in the broader consequences of the movements of plants and their associated microbiomes between habitats, whether transitions between emerged and submerged environments, or introductions of non-native plants to new locations.
